But I have one mroe doubt that...In a single sheet suppose i want to siaplay values for 2014 and 2015 as well....But condition is that for 2014 I have to show only 1 month value (say DEC) and for 2015 i have to show the latest month data....For this i have created below static expression::

IF [Year]=2014 THEN

IIF([Month]=8,"Yes","No")

ELSE

IIF([Month]=2,"Yes","No")

END.

But i want to do this dynamically....can we achieve this by using a Month or Date field??
